The FAA has recently made a proposal to require reduced time-in-service for TITAN® brand 520/550 cylinder assemblies produced between 2000 and 2009, based on Service Difficulty Reports (SDR) of some 30 cylinders.
ECi is challenging the proposal and working to have it modified, as ECi has engineering data and analysis showing the root cause of the failures being related to over-temperature and similar operating conditions.
We believe these conditions are at the core of these 30 incidents, and also the probable root cause of more than 1200 similar cylinder incidents related to other manufacturers.
Voice Your Comments to the FAA
It is impossible to respond to, and accurately submit a comment on unpublished, unsubstantiated data. Unfortunately, the FAA has not provided any data in support of its proposal. The only information available on which to comment is the general statement, "numerous Cracks...". Therefore the most effective comments to the FAA will address the issue of cracking directly, by providing evidence of the scope and prevalence of cracking throughout cylinders of all manufactures.
Many people mistakenly believe that their comment (technically called a "Public Submission") or letter posted on the NPRM/docket constitutes a “vote” regarding the issues concerning them.
Although public support or opposition may help guide important public policies, agencies make determinations for a proposed action based on sound reasoning and documented evidence, not a majority of votes. A single, well-supported comment may carry more weight than a thousand form letters.
